Przewlekła encefalopatia pourazowa

Przewlekła encefalopatia pourazowa
Objawy

Przewlekła encefalopatia pourazowa (CTE) to postępująca, nieodwracalna choroba neurodegeneracyjna mózgu, powiązana z powtarzającymi się urazami głowy. Objawy rozwijają się z opóźnieniem, zwykle około 10 lat po ekspozycji na urazy, i manifestują się w dwóch formach: młodzieńczej z dominującymi zaburzeniami nastroju i zachowania (depresja, lęk, impulsywność) oraz późnej, około 60. roku życia, z przewagą deficytów poznawczych prowadzących do demencji. CTE charakteryzuje się czterema stadami progresji, od łagodnych objawów takich jak bóle głowy, problemy z koncentracją i łagodna agresja, przez nasilające się zaburzenia nastroju, pamięci i funkcji wykonawczych, aż do zaawansowanej demencji, parkinsonizmu i zaburzeń motorycznych. Około 75% pacjentów w stadium III wykazuje znaczące upośledzenie poznawcze. Objawy dzielą się na cztery kategorie: poznawcze (utrata pamięci krótkotrwałej, zaburzenia funkcji wykonawczych, dezorientacja), behawioralne (wybuchowość, agresja, zmiany osobowości), nastroju (depresja, labilność emocjonalna) oraz motoryczne (parkinsonizm, ataksja, dyzartria). Zaburzenia snu, w tym zaburzenia zachowania w fazie REM i bezdech senny, są często współwystępujące.

Objawy i progresja przewlekłej encefalopatii pourazowej

Przewlekła encefalopatia pourazowa (Chronic Traumatic Encephalopathy, CTE) jest postępującą chorobą neurodegeneracyjną mózgu, która najprawdopodobniej jest spowodowana powtarzającymi się urazami głowy. Prowadzi ona do śmierci komórek nerwowych w mózgu, określanej jako degeneracja. CTE pogarsza się z czasem i ma charakter nieodwracalny.¹²³

Rozwój objawów CTE

Charakterystyczną cechą CTE jest to, że objawy nie pojawiają się bezpośrednio po urazie głowy. Eksperci uważają, że rozwijają się one w ciągu lat lub dekad po powtarzających się urazach głowy.⁴⁵ Symptomy często zaczynają pojawiać się stopniowo, zazwyczaj około 10 lat po doznaniu powtarzających się urazów głowy.⁶ Badania wskazują, że objawy CTE mogą pojawić się u osób młodych, ale najczęściej manifestują się w średnim lub późnym wieku.⁷⁸

Objawy CTE mogą się stopniowo nasilać lub pozostawać na tym samym poziomie przez lata, zanim ulegną pogorszeniu.⁹ Wzorzec postępowania objawów różni się między pacjentami, ale generalnie obserwuje się stałą progresję symptomów, która ostatecznie prowadzi do poważnych zaburzeń funkcji poznawczych i motorycznych.¹⁰

Dwie formy występowania objawów

Eksperci uważają, że objawy CTE występują w dwóch różnych formach:¹¹¹²

Pierwsza forma objawia się w młodszym wieku (późne lata 20. i wczesne 30.) i powoduje problemy ze zdrowiem psychicznym oraz zaburzenia zachowania. Objawy tej formy obejmują depresję, stany lękowe, zachowania impulsywne i agresję.¹³¹⁴
Druga forma powoduje objawy w późniejszym okresie życia, około 60. roku życia. Te objawy obejmują problemy z pamięcią i myśleniem, które prawdopodobnie postępują do demencji.¹⁵¹⁶

Badania pokazują, że młodsi pacjenci częściej doświadczają objawów behawioralnych, takich jak niepokój, depresja, wybuchy gniewu i zaburzenia snu. Ich problemy poznawcze dotyczą głównie utraty pamięci krótkotrwałej i trudności w funkcjach wykonawczych.¹⁷

Starsi pacjenci częściej prezentują postępujące zaburzenia poznawcze podobne do choroby Alzheimera, z wyraźnymi deficytami pamięci i spadkiem zdolności poznawczych w miarę upływu czasu.¹⁸

Stadia przewlekłej encefalopatii pourazowej

Przewlekła encefalopatia pourazowa charakteryzuje się czterema stadiami progresji, które odzwierciedlają nasilenie objawów wraz z postępem choroby.¹⁹²⁰

Stadium I

We wczesnym stadium CTE objawy są subtelne i mogą być początkowo niezauważalne:²¹²²

Bóle głowy
Problemy z koncentracją i uwagą
Krótkotrwała utrata pamięci
Łagodna agresja i depresja
Problemy z funkcjami wykonawczymi (planowanie, uwaga, koncentracja, wielozadaniowość)²³

Stadium II

W drugim stadium objawy stają się bardziej widoczne:²⁴²⁵

Ciężka depresja
Wahania nastroju
Krótkotrwała utrata pamięci
Wybuchy gniewu
U niektórych pacjentów pojawia się impulsywność, myśli samobójcze i trudności językowe²⁶

Stadium III

W stadium trzecim pacjenci wykazują znaczne pogorszenie funkcji poznawczych:²⁷²⁸

Utrata pamięci
Zaburzenia funkcji wykonawczych
Wybuchowość
Problemy z uwagą i koncentracją
Depresja i wahania nastroju
Trudności przestrzenno-wzrokowe
Agresja
Apatia²⁹

Około 75% osób w stadium III jest uznawanych za poznawczo upośledzonych.³⁰

Stadium IV

Czwarte stadium to najbardziej zaawansowana forma choroby:³¹³²

Poważna utrata zdolności poznawczych i pamięci prowadząca do pełnoobjawowej demencji
Głęboka utrata uwagi i koncentracji
Paranoja
Depresja
Zaburzenia funkcji wykonawczych
Trudności językowe
Wybuchowość i agresja
Problemy z chodzeniem i równowagą
Trudności przestrzenno-wzrokowe
Parkinsonizm (zaburzenia ruchu)³³³⁴

Główne kategorie objawów CTE

Objawy CTE można podzielić na cztery główne kategorie: poznawcze, behawioralne, nastroju i motoryczne.³⁵³⁶

Objawy poznawcze

Do objawów poznawczych przewlekłej encefalopatii pourazowej należą:³⁷³⁸

Utrata pamięci – szczególnie pamięci krótkotrwałej, problemy z zapamiętywaniem nowych informacji, powtarzanie tych samych pytań
Zaburzenia funkcji wykonawczych – trudności z planowaniem, organizacją i zarządzaniem czasem
Problemy z uwagą i koncentracją – trudności z utrzymaniem uwagi na zadaniach
Zaburzenia językowe – problemy z formułowaniem myśli, trudności w rozumieniu lub interpretowaniu informacji
Trudności przestrzenno-wzrokowe – problemy z orientacją przestrzenną
Dezorientacja i splątanie – gubienie się, nieznajomość pory dnia
Postępująca demencja w zaawansowanych stadiach³⁹⁴⁰

Objawy behawioralne

Objawy behawioralne w CTE obejmują:⁴¹⁴²

Wybuchowość – nagłe wybuchy gniewu i agresji, w tym przemoc fizyczna lub słowna
Problemy z kontrolą impulsów – podejmowanie ryzyka bez rozważania konsekwencji
Agresywne zachowanie – często nietypowe dla danej osoby
Nieodpowiednie zachowania społeczne – trudności w respektowaniu norm społecznych
Paranoja – nieuzasadniony lęk i podejrzliwość
Zmiany osobowości – zachowania odbiegające od wcześniejszych cech charakteru
Nadużywanie substancji psychoaktywnych⁴³⁴⁴

Objawy związane z nastrojem

Do objawów związanych z nastrojem zalicza się:⁴⁵⁴⁶

Depresja – utrzymujące się uczucie smutku i beznadziejności
Stany lękowe – ciągły niepokój i napięcie
Wahania nastroju – nagłe zmiany nastroju
Myśli i zachowania samobójcze
Apatia – brak zainteresowania aktywnościami, które wcześniej sprawiały przyjemność
Labilność emocjonalna – niestabilność emocjonalna
Drażliwość – obniżony próg frustracji⁴⁷⁴⁸

Objawy motoryczne

Objawy motoryczne, które występują zwłaszcza w późniejszych stadiach CTE, obejmują:⁴⁹⁵⁰

Parkinsonizm – drżenia, spowolnienie ruchowe i sztywność mięśniowa
Problemy z równowagą i koordynacją – niestabilny chód, zwiększone ryzyko upadków
Ataksja – niezborność ruchów
Dyzartria – zaburzenia mowy, mowa niewyraźna
Dysfagia – trudności z połykaniem (rzadziej)
Spastyczność – zwiększone napięcie mięśniowe⁵¹⁵²

Specyficzne cechy progresji CTE

Progresja uzależniona od wieku

Progresja objawów CTE wykazuje pewne zależności związane z wiekiem pacjenta:⁵³

Młodsi pacjenci (20-30 lat) częściej doświadczają najpierw objawów nastroju i zachowania
Starsi pacjenci (powyżej 60 lat) częściej zaczynają od zaburzeń poznawczych
Demencja występuje częściej u starszych pacjentów i jest związana z progresją zależną od wieku⁵⁴

Badania sugerują, że zaburzenia snu, w szczególności objawy związane z zaburzeniami zachowania w fazie REM, mogą być związane z patologią CTE.⁵⁵

Rola zaburzeń snu

Zaburzenia snu są często obserwowane u pacjentów z CTE i mogą obejmować:

Bezsenność lub nadmierna senność
Zaburzenia zachowania w fazie REM
Bezdech senny – który częściej występuje u sportowców uprawiających sporty kontaktowe i może również powodować objawy poznawcze⁵⁶⁵⁷

Choroby współistniejące

U niektórych pacjentów z CTE mogą rozwinąć się również inne schorzenia neurodegeneracyjne:⁵⁸

Choroba neuronu ruchowego – podobna do stwardnienia zanikowego bocznego (ALS)
Choroba Parkinsona – z charakterystycznymi objawami, takimi jak drżenie, spowolnienie i sztywność
Inne zaburzenia degeneracyjne mózgu – które mogą nakładać się na objawy CTE⁵⁹⁶⁰

Czynniki wpływające na przebieg choroby

Przebieg CTE i nasilenie objawów mogą być modyfikowane przez różne czynniki:⁶¹

Czynniki indywidualne

Wiek pierwszego urazu – urazy w młodszym wieku mogą zwiększać ryzyko wcześniejszego wystąpienia objawów
Liczba i nasilenie urazów – istnieje zależność między ilością urazów a ciężkością objawów
Predyspozycje genetyczne – mogą wpływać na podatność na rozwój CTE i jej przebieg
Choroby współistniejące – inne schorzenia mogą nasilać objawy CTE⁶²⁶³

Typ aktywności z ryzykiem urazów

Różne aktywności wiążą się z różnym poziomem ryzyka rozwoju CTE:⁶⁴

Sporty kontaktowe – futbol amerykański, boks, hokej, rugby, soccer
Służba wojskowa – ekspozycja na wybuchy i inne urazy
Inne aktywności wiążące się z powtarzającymi się urazami głowy⁶⁵⁶⁶

Możliwości leczenia wpływające na progresję

Obecnie nie istnieje lekarstwo na CTE, ale niektóre interwencje mogą wpłynąć na przebieg objawów:⁶⁷

Leczenie objawowe – farmakoterapia ukierunkowana na konkretne objawy, np. leki przeciwdepresyjne, przeciwlękowe
Leki na demencję – takie jak Aricept (donepezil) i Namenda (memantyna) mogą łagodzić utratę pamięci i dezorientację
Terapie niefarmakologiczne – terapia poznawcza, fizjoterapia, terapia zajęciowa
Styl życia – regularna aktywność fizyczna, zdrowa dieta, zaangażowanie społeczne mogą opóźnić progresję objawów⁶⁸⁶⁹

Diagnostyka i wyzwania związane z CTE

Jednym z największych wyzwań związanych z CTE jest fakt, że obecnie definitywne rozpoznanie możliwe jest tylko pośmiertnie, podczas autopsji mózgu.⁷⁰⁷¹ To sprawia, że monitorowanie progresji choroby u żyjących pacjentów jest niezwykle trudne.⁷²

Trudności diagnostyczne obejmują również:

Nakładanie się objawów z innymi schorzeniami – objawy CTE są podobne do objawów innych chorób neurodegeneracyjnych, takich jak choroba Alzheimera, co utrudnia diagnostykę różnicową⁷³
Zróżnicowany przebieg kliniczny – objawy mogą różnić się znacznie między pacjentami⁷⁴
Długi okres utajenia – objawy mogą pojawić się wiele lat po urazach, co utrudnia ustalenie związku przyczynowego⁷⁵

Badacze pracują nad metodami diagnozowania CTE u żyjących pacjentów, co pozwoliłoby na lepsze monitorowanie progresji choroby i skuteczniejsze interwencje terapeutyczne.⁷⁶

Podsumowanie progresji CTE

Przewlekła encefalopatia pourazowa jest postępującą, nieuleczalną chorobą neurodegeneracyjną, której objawy rozwijają się stopniowo w ciągu lat lub dekad po powtarzających się urazach głowy.⁷⁷⁷⁸

Choroba charakteryzuje się czterema stadiami progresji, od łagodnych objawów poznawczych i emocjonalnych w pierwszym stadium, do ciężkiej demencji i zaburzeń motorycznych w stadium czwartym.⁷⁹⁸⁰

Objawy CTE można podzielić na cztery główne kategorie: poznawcze, behawioralne, nastroju i motoryczne, przy czym wzorzec progresji może różnić się w zależności od wieku pacjenta i innych czynników indywidualnych.⁸¹⁸²

Chociaż nie ma obecnie lekarstwa na CTE, właściwe leczenie objawowe i zmiany stylu życia mogą pomóc w zarządzaniu objawami i poprawie jakości życia pacjentów.⁸³⁸⁴

Badania nad CTE są nadal w toku, a naukowcy dążą do lepszego zrozumienia czynników wpływających na rozwój i progresję choroby oraz opracowania metod wczesnej diagnostyki i skuteczniejszych strategii terapeutycznych.⁸⁵⁸⁶

Chronic traumatic encephalopathy (CTE) is a brain disorder likely caused by repeated head injuries. It causes the death of nerve cells in the brain, known as degeneration. CTE gets worse over time. […] Symptoms of CTE are thought to include trouble with thinking and emotions, physical problems, and other behaviors. It’s thought that these develop years to decades after head trauma occurs. […] CTE symptoms don’t develop right after a head injury. Experts believe that they develop over years or decades after repeated head trauma. […] Experts also believe that CTE symptoms appear in two forms. In early life between the late 20s and early 30s, the first form of CTE may cause mental health and behavioral issues. Symptoms of this form include depression, anxiety, impulsive behavior and aggression. The second form of CTE is thought to cause symptoms later in life, around age 60. These symptoms include memory and thinking problems that are likely to progress to dementia. […] The full list of signs to look for in people with CTE at autopsy is still unknown.

#2 Chronic Traumatic Encephalopathy (CTE): Symptoms & Treatment
https://my.clevelandclinic.org/health/diseases/17686-chronic-traumatic-encephalopathy-cte
The symptoms of chronic traumatic encephalopathy can disrupt processes throughout your brain. […] As this condition worsens, it can cause disruptive or aggressive behavior. […] The symptoms of CTE tend to develop slowly and get worse over time. […] Common symptoms of CTE can include: Trouble concentrating or focusing (mild cognitive impairment). […] Changes in behavior, including sudden outbursts or explosions of anger. […] Other symptoms that can occur include: Increasingly aggressive behavior. […] Self-harming thoughts and behaviors (including thinking about and attempting suicide). […] CTE is a degenerative brain disease. That means its progressive, and the symptoms will get worse over time. […] CTE is a permanent, lifelong condition. […] Currently, the available research and understanding of CTE indicate this condition isnt deadly on its own. Instead, it causes other health concerns that negatively affect your health and well-being. […] When the effects of this condition get severe enough, it can lead to dysphagia, which is when you have trouble swallowing.

#5 Going through the Stages of CTE | The CTE Society
https://www.ctesociety.org/latest_news/going-through-the-stages-of-cte/
One of the challenging aspects of Chronic Traumatic Encephalopathy (CTE) is that its onset can happen years after injury. […] Here are some of the most common symptoms experienced in the four progressive stages of CTE: […] This first stage is most commonly marked by headaches, and loss of attention and concentration. Some individuals experience short-term memory problems, depression, aggressive tendencies, explosivity, and executive function issues. […] Depression, moods swings, headache, and short-term memory loss top the list of most frequently experienced symptoms in Stage II. A smaller percentage of patients experience executive dysfunction, impulsivity, suicidal thoughts and language challenges during this stage. […] Topping this stage is memory loss, executive dysfunction, explosivity, attention and concentration issues, depression, mood swings, visuospatial difficulties and aggression. Apathy also appears in this stage, and 75% of the Stage III individuals studied were considered cognitively impaired.
#6 Chronic traumatic encephalopathy
https://www.nhs.uk/conditions/chronic-traumatic-encephalopathy/
Chronic traumatic encephalopathy (CTE) is a brain condition thought to be linked to repeated head injuries and blows to the head. It slowly gets worse over time and leads to dementia, but the right help and support can manage the symptoms. […] Early symptoms of chronic traumatic encephalopathy may not be noticeable at first. […] Symptoms include: short-term memory loss, confusion, such as getting lost or not knowing what time of day it is, difficulties with planning and organisation, problems with movement. […] Symptoms usually start gradually, often around 10 years after having repeated head injuries. […] The symptoms may get worse gradually or stay the same for years before getting worse. […] Chronic traumatic encephalopathy (CTE) cannot be cured, but medicines and other treatments can help your symptoms.
#7 Frequently Asked Questions | CTE Center
https://www.bu.edu/cte/about/frequently-asked-questions/
The symptoms of CTE include memory loss, confusion, impaired judgment, impulse control problems, aggression, depression, anxiety, suicidality, parkinsonism, and, eventually, progressive dementia. These symptoms often begin years or even decades after the last brain trauma or end of active athletic involvement. […] The symptoms of CTE generally do not present until years or decades after the brain trauma occurred or after one stops actively playing contact sports. […] Just because you have some or many of the symptoms of CTE does not necessarily mean that you have the disease itself. […] Unfortunately, at this time there is no cure for CTE. However, the symptoms of CTE, such as depression and anxiety, can be treated individually.
#8 Chronic traumatic encephalopathy – Wikipedia
https://en.wikipedia.org/wiki/Chronic_traumatic_encephalopathy
Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease linked to repeated trauma to the head. The encephalopathy symptoms can include behavioral problems, mood problems, and problems with thinking. The disease often gets worse over time and can result in dementia. […] Symptoms of CTE, which occur in four stages, generally appear eight to ten years after an individual experiences repetitive mild traumatic brain injuries. First-stage symptoms are confusion, disorientation, dizziness, and headaches. Second-stage symptoms include memory loss, social instability, impulsive behavior, and poor judgment. Third and fourth stages include progressive dementia, movement disorders, hypomimia, speech impediments, sensory processing disorder, tremors, vertigo, deafness, depression and suicidality.

#12 Chronic Traumatic Encephalopathy (CTE)
https://www.webmd.com/brain/what-is-chronic-traumatic-encephalopathy-cte
You may have: […] These conditions usually begin years, sometimes decades, after your last brain injury or when you stopped playing. Experts think CTE symptoms show up in two ways during different periods of your life. The first form appears in your late 20s or early 30s and causes problems with mental health and behavior. You may have depression, anxiety, aggression, and impulse control issues. […] Later, around age 60, is when the second form may crop up, causing trouble with memory and thinking. Some symptoms are similar to those seen in people with Alzheimer’s or Parkinson’s disease, which makes it hard to diagnose. Let your doctor know about any head injuries you’ve had, no matter how long ago, and when your symptoms started.

#16 Current Understanding of Chronic Traumatic Encephalopathy
https://pmc.ncbi.nlm.nih.gov/articles/PMC4255271/
The first type of clinical presentation initially presents with mood and behavioral symptoms earlier in life (mean age approximately 35) and progresses to include cognitive symptoms later in the disease course. The second clinical presentation begins with cognitive impairment later in life (mean age approximately 60), which may progress to include mood and behavioral symptoms. […] Earlier cases of CTE tended to report a higher prevalence of motor features than more recent reports. […] The question of suicide in CTE remains contentious. […] All efforts to define the clinical presentation of CTE are also limited due to the lack of in vivo diagnosis and use of retrospective reviews of case reports or family interviews.
#17 Suspected CTE Treatments | Concussion Legacy Foundation
https://concussionfoundation.org/cte-resources/treatments/
There are many therapies available to treat the symptoms associated with suspected Chronic Traumatic Encephalopathy (CTE) that allow patients to have a better quality of life. […] When it comes to choosing treatments, there have been very few scientific studies on how to treat the clinical symptoms of CTE and even fewer clinical trials exploring innovative therapies that could slow or stop the progression of the disease. […] The management of CTE symptoms requires a comprehensive approach that addresses both physical and cognitive symptoms. Individualized care plans focus on improving the quality of life for those affected, while cognitive therapies help improve functioning and assist individuals in adapting to their limitations. […] Younger individuals often encounter a cluster of behavioral issues, including anxiety, depression, rage, and sleep disturbances. Their cognitive challenges primarily involve short-term memory loss and difficulty in executive functions, which disrupt their daily living and normal activities.
#18 Suspected CTE Treatments | Concussion Legacy Foundation
https://concussionfoundation.org/cte-resources/treatments/
Older patients often present with progressive cognitive impairments similar to Alzheimerâs disease, with pronounced memory deficits and a decline in cognitive abilities over time. These symptoms can pose significant complications in diagnosis, as they closely mimic other neurodegenerative conditions. […] According to Dr. Cantu, the pharmacological factors for managing CTE include a range of medications, each targeting specific symptom clusters.

Chronic traumatic encephalopathy (CTE) is increasingly in the news often in connection to severe mood and behavior changes in former athletes. […] Like Alzheimers and Parkinson’s disease, CTE is a neurodegenerative condition. This brain disease occurs when the nerve cells that help you think, feel, and move gradually break down. When these cells stop working, patients may experience personality changes and lose memory and muscle control. […] CTE is characterized by four stages of symptoms: Stage 1: Short-term memory loss; mild aggression and depression; headaches. […] Stage 2: Severe depression, outbursts, and mood swings. […] Stage 3: Aggression; apathy; memory loss; lack of spatial awareness; executive dysfunction (inability to successfully complete activities that require time management, organization, and problem-solving).
#20 What Is Chronic Traumatic Encephalopathy (CTE)?
https://www.emedicinehealth.com/what_is_chronic_traumatic_encephalopathy_cte/article_em.htm
Chronic traumatic encephalopathy (CTE) is a brain condition affecting the mood, memory, behavior, and cognitive function, which is caused by repetitive hits to the head sustained over many years. […] Chronic traumatic encephalopathy (CTE) is a progressive and degenerative brain condition caused by repetitive hits to the head sustained over many years. […] Symptoms of chronic traumatic encephalopathy (CTE) affect the functioning of the brain and eventually lead to dementia. The symptoms of CTE tend to start a few years after a person has stopped playing a sport or after the activity that causes repeated hits to the head. […] As CTE progresses, symptoms may include: Significant memory problems, Slurred speech (dysarthria), Parkinsonism, Difficulty eating or swallowing (dysphagia) (rare).

Chronic Traumatic Encephalopathy (CTE) is a debilitating neurodegenerative disease, which has been increasingly reported in athletes, especially American football players, as well as military veterans in combat settings, commonly as a result of repetitive mild traumatic brain injuries (TBIs). […] Clinically, CTE has a more subtle presentation, as patients often present with two distinct phenotypes, with one subtype initially presenting with affective changes, and the other subtype with more cognitive impairment. […] The following paragraphs outline attempts of characterization of CTE symptoms in the various stages of the disease process. According to McKee’s classification, in stage I, a typical CTE patient is asymptomatic, or may complain of mild short term memory deficits and depressive symptoms. Mild aggression may be observed. In Stage II, the mood and behavioral symptoms could include behavioral outbursts and more severe depressive symptoms. In Stage III, patients typically present with more cognitive deficits, including memory loss, executive functioning deficits, visuospatial dysfunction, and apathy. In Stage IV, patients present with advanced language deficits, psychotic symptoms including paranoia, motor deficits, and parkinsonism.

The behavioral and psychiatric domain included aggression, depression, apathy, impulsivity, delusions including paranoia, and suicidality. The cognitive domain included diminished attention and concentration, memory deficits, executive functioning deficits, visuospatial dysfunction, language deficits, and dementia. Finally, the motor features consisted of dysarthria, gait abnormalities, ataxia and incoordination, spasticity, and parkinsonism features such as tremors. […] The proposed TES diagnosis also contained temporal qualifiers and included progressive course, stable course, and unknown/inconsistent course.

https://pmc.ncbi.nlm.nih.gov/articles/PMC4255271/
Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease thought to be associated with a history of repetitive head impacts […] Clinical symptoms of CTE generally present years or decades after exposure to trauma. […] Evidence to-date suggests that CTE presents clinically with symptoms in one or more of four possible domains: mood, behavior, cognition, and motor. […] Commonly noted mood features include depression, irritability, and hopelessness. Behavioral features may include impulsivity, explosivity, and aggression. Cognitive features can include memory impairment, executive dysfunction, and in severe cases dementia. Motor features, including parkinsonism, ataxia, and dysarthria, appear in a subset of cases, predominantly boxers. […] Two distinct clinical presentations of CTE have been described in a recent study by Stern et al., substantiating evidence from earlier literature regarding this possibility.

Chronic traumatic encephalopathy is a type of neurodegenerative disease that may lead to cognitive impairment and dementia. Affected individuals typically display signs like disorientation, confused thinking, and problems with mood and memory. […] At present, CTE can only be identified by physically examining the brain of an affected individual after their death. This means no combination of symptoms can be used to definitively diagnose a living individual with this condition. […] However, a 2014 review of more than 200 confirmed cases of CTE identified many common symptoms of traumatic encephalopathy syndrome, a pathology that could indicate the presence of CTE. The symptoms can be grouped into four categories: Cognitive symptoms, Mood symptoms, Behavioral symptoms, Motor symptoms. […] Many people later found to have CTE show signs of impaired cognitive abilities, such as difficulties with attention and focus, memory, keeping track of complex tasks, visual and spatial perception, speech, writing, and general language use, shifting between ideas and concepts, and self-awareness. These challenges typically worsen over time, and in many cases, they eventually progress to dementia. Cognitive impairments tend to be strongly associated with the brain pathology that defines CTE and may be among its most characteristic signs.

Chronic traumatic encephalopathy (CTE) is a progressive and fatal brain disease associated with repeated traumatic brain injuries (TBIs), including concussions and repeated blows to the head. […] Studies have shown that people who experience TBI in early to midlife are two to four times more at risk of developing dementia in late life. This risk appears to be much higher in people with several TBIs, although more research is needed to confirm this. […] Not all scientists agree on the symptoms of CTE, but the disease has been associated with: memory and thinking problems, confusion, personality changes, and/or erratic behavior including aggression, depression and even suicidal thinking. […] Other symptoms may include problems paying attention and organizing thoughts as well as difficulty with balance and motor skills. People may not experience these potential signs of CTE until years or decades after brain injuries occur.
#40 Chronic Traumatic Encephalopathy | Memory and Aging Center
https://memory.ucsf.edu/dementia/chronic-traumatic-encephalopathy
Thinking and behavior changes in CTE usually begin very mildly, and the person and their family may not notice significant changes at first. Early symptoms may include mild memory loss, headaches, irritable mood, slurred speech, or unsteadiness when walking. People with CTE may have trouble concentrating, organizing or planning tasks, remembering answers to questions they ask or doing more than one task at a time. […] Later in the disease, memory, mood, behavior, and problems with speech. People with CTE may become depressed or anxious and may act more aggressively and inappropriately in social situations. They may get lost. Speech may also get worse, and people with CTE may become harder and harder to understand. Worsening problems with walking and balance may increase the risk for falls late in the disease. […] A person with CTE can live many years with the disease.

Disturbances in mood and emotion can also be commonly observed in people with chronic traumatic encephalopathy, including mood swings, irritability, apathy or loss of interest in activities, flattened emotions, a sense of hopelessness, mania or euphoria, and suicidal thoughts and intentions. […] Atypical patterns of behavior can also be common in people who are later found to have had CTE, such as socially inappropriate behavior, lack of impulse control, aggression or explosive anger, personality changes, paranoia, social withdrawal, and exaggerated boastfulness. […] Some people with CTE may display difficulties with movement, though these tend to be less common and may represent a distinct subtype of traumatic encephalopathy syndrome. These symptoms can include poor motor control and coordination, gait disturbances, muscle weakness, parkinsonism (tremors, stiffness, and slowed movements), and facial paralysis and difficulty speaking.
#43 Chronic traumatic encephalopathy – Wikipedia
https://en.wikipedia.org/wiki/Chronic_traumatic_encephalopathy
The condition manifests as dementia, or declining mental ability, problems with memory, dizzy spells or lack of balance to the point of not being able to walk under one’s own power for a short time and/or Parkinsonism, or tremors and lack of coordination. It can also cause speech problems and an unsteady gait. Patients with CTE may be prone to inappropriate or explosive behavior and may display pathological jealousy or paranoia. […] No cure exists for CTE, and it cannot be diagnosed until a post-mortem autopsy is performed. Treatment is supportive as with other forms of dementia. Those with CTE-related symptoms may receive medication and non-medication-related treatments. Currently, there is no way to stop or slow the development of chronic traumatic encephalopathy (CTE). However, medications like Aricept (donepezil) and Namenda (memantine) can mitigate memory loss and confusion, and Aricept can improve memory, motivation, and attention by increasing acetylcholine levels in the brain. […] Rates of disease are about 30% among those with a history of multiple head injuries. Population rates, however, are unclear. Tracking the epidemiology of CTE is difficult due to the inability to diagnose this syndrome during life.

CTE is a progressive disorder; symptoms can take many years to develop. When left undiagnosed and untreated, symptoms worsen over time. The most telling signs of CTE include […] In severe cases, CTE is likely to cause more troubling symptoms, such as […] Many brain disorders share similar symptoms with CTE. Exhibiting the above symptoms isn’t a sure sign that you have the condition. In some fatal cases of CTE, people with the disorder showed no symptoms while alive. […] CTE typically develops in four stages: […] The fourth stage results in psychotic symptoms, difficulty speaking coherently, and severe loss of motor skills. […] There is currently no cure for CTE, but some of its symptoms can be managed, especially when an early diagnosis is made. […] CTE is a progressive and degenerative brain condition that can be fatal. More research needs to be done to help understand the condition and effectively treat it. The good news is that CTE is preventable. […] One of the more severe symptoms of CTE is suicidal thoughts and behavior.

https://www.cognitivefxusa.com/blog/post-traumatic-brain-injury-syndrome
Chronic traumatic encephalopathy (CTE) is a neurodegenerative disorder in which patients get progressively worse; it may develop in patients who suffered repeated brain injuries over several years. […] Common symptoms of CTE include difficulties concentrating or focusing, headaches, short-term memory problems, changes in behavior, including sudden outbursts or explosions of anger, depression and anxiety, aggression, executive dysfunction, cognitive impairment, trouble speaking clearly, tremors and other kinds of uncontrollable muscle movements, balance problems, loss of coordination, self-harming thoughts and behaviors, impaired judgment, and confusion. […] At the moment, the only way to confirm CTE is with a postmortem neuropathological analysis. Doctors make a presumptive diagnosis based on symptoms and a physical and neurological/neuropsychological exam. They also review how many times the patient suffered brain injuries and may recommend certain brain scans, such as a CT or MRI scan, to rule out other conditions.

Here, we present the advances in the neuropathological diagnosis of CTE culminating with the development of the NINDSNIBIB criteria, the multiple international studies that have used these criteria to report CTE in hundreds of contact sports players and others, and the evidence for a robust doseresponse relationship between RHI and CTE. […] The clinical features associated with CTE pathology include cognitive, mood, behavior, and motor impairments, with dementia common in severe disease. […] Younger individuals tend to present with mood and behavior symptoms, whereas older individuals more commonly present with cognitive impairment and executive dysfunction. […] The presence of dementia followed an age-dependent progression, and older age at death was associated with increased odds for having dementia. […] The preponderance of the evidence suggests a high likelihood of a causal relationship between RHI and CTE, a conclusion that is strengthened by the absence of any evidence for plausible alternative hypotheses.

The first type of clinical presentation initially presents with mood and behavioral symptoms earlier in life (mean age approximately 35) and progresses to include cognitive symptoms later in the disease course. The second clinical presentation begins with cognitive impairment later in life (mean age approximately 60), which may progress to include mood and behavioral symptoms. […] Earlier cases of CTE tended to report a higher prevalence of motor features than more recent reports. […] The question of suicide in CTE remains contentious. […] All efforts to define the clinical presentation of CTE are also limited due to the lack of in vivo diagnosis and use of retrospective reviews of case reports or family interviews.

Related movement disorders. Some people develop motor neurone disease (MND) or Parkinsons disease in association with CTE. […] Researchers identified these symptoms by interviewing family members of people who were confirmed to have CTE. […] This is because CTE cant currently be diagnosed while a person is alive. The diagnosis is only confirmed by looking at the persons brain tissue after they have passed away. […] Research has also suggested that there are possibly two clinical presentations of CTE. Some people experience behavioural and mood symptoms first, while others experience cognitive symptoms first. […] The variation in CTE is partially the reason that it is difficult to diagnose. If someone develops symptoms of depression and anger issues in their 20s or 30s, it may be misdiagnosed as a psychiatric disorder.

CTE can have devastating impacts on an individual and their family. Family members of people who were found to have CTE reported that they had noticed changes in the person’s behavior, thinking, and emotions for some time. These problems often became serious enough to get in the way of their loved one’s family, social, or work-related activities. People with CTE are at risk for poor impulse control and, in some cases, suicide. CTE eventually can lead to advanced dementia, Parkinson’s disease, and a movement disorder similar to amyotrophic lateral sclerosis, or ALS (formerly known as Lou Gehrig’s disease).

The prognosis for chronic traumatic encephalopathy varies from person to person and depends on several factors including the severity of the disease, the age at which symptoms first appear, and the presence of other medical conditions. […] In general, CTE is a progressive disease that tends to worsen over time. However, the rate of progression and the severity of symptoms can vary widely among individuals.

Over the last 17 years, there has been a remarkable increase in scientific research concerning chronic traumatic encephalopathy (CTE). […] CTE has been reported in amateur and professional athletes, including a bull rider, boxers, wrestlers, and American, Canadian, and Australian rules football, rugby union, rugby league, soccer, and ice hockey players. […] Presently, CTE can be definitively diagnosed only by postmortem neuropathological examination; the corresponding clinical condition is known as traumatic encephalopathy syndrome (TES). […] Over 97% of CTE cases published have been reported in individuals with known exposure to repetitive head impacts (RHI), including concussions and nonconcussive impacts, most often experienced through participation in contact sports. […] There is a robust doseresponse relationship between CTE and years of American football play, a relationship that remains consistent even when rigorously accounting for selection bias.

Several complications can occur immediately or soon after a traumatic brain injury. Severe injuries increase the risk of a greater number of and more-severe complications. […] Sometimes, any or several of these symptoms might linger for a few weeks to a few months after a traumatic brain injury. When a combination of these symptoms lasts for an extended period of time, this is generally referred to as persistent post-concussive symptoms. […] The relationship between degenerative brain diseases and brain injuries is still unclear. But some research suggests that repeated or severe traumatic brain injuries might increase the risk of degenerative brain diseases. But this risk can’t be predicted for an individual and researchers are still investigating if, why and how traumatic brain injuries might be related to degenerative brain diseases.

The best way to prevent CTE is to avoid activities that cause head injuries, and athletes have a responsibility to tell a coach or trainer if they have concussive symptoms after a head injury. […] What is clear is that most exposures to repetitive head impacts occur in athletes and veterans at relatively young ages, rarely past early adulthood. The head injuries for the most part stop whenever someone ends their athletic career or is discharged from the military, yet the first symptoms associated with CTE may not occur until years or decades later. […] Unfortunately, there isn’t, and there is no cure. Doctors will treat individual symptoms, like depression or anxiety, and we know things like staying physically active, socially engaged, eating a healthy diet and getting quality sleep will help keep the brain healthy during life. But with CTE, we try to use harm reduction strategies, such as educating people on the risks that could lead to the disease. […] The best way to prevent CTE is to avoid activities that cause head injuries. For high-contact sports, this means limiting contact to the head, and athletes have a responsibility to tell a coach or trainer if they have concussive symptoms after a head injury.

The condition manifests as dementia, or declining mental ability, problems with memory, dizzy spells or lack of balance to the point of not being able to walk under one’s own power for a short time and/or Parkinsonism, or tremors and lack of coordination. It can also cause speech problems and an unsteady gait. Patients with CTE may be prone to inappropriate or explosive behavior and may display pathological jealousy or paranoia. […] No cure exists for CTE, and it cannot be diagnosed until a post-mortem autopsy is performed. Treatment is supportive as with other forms of dementia. Those with CTE-related symptoms may receive medication and non-medication-related treatments. Currently, there is no way to stop or slow the development of chronic traumatic encephalopathy (CTE). However, medications like Aricept (donepezil) and Namenda (memantine) can mitigate memory loss and confusion, and Aricept can improve memory, motivation, and attention by increasing acetylcholine levels in the brain. […] Rates of disease are about 30% among those with a history of multiple head injuries. Population rates, however, are unclear. Tracking the epidemiology of CTE is difficult due to the inability to diagnose this syndrome during life.
#68 How to Tackle Post Traumatic Brain Injury Syndrome
https://www.cognitivefxusa.com/blog/post-traumatic-brain-injury-syndrome
Just as dementia is not reversible, there’s no cure for CTE. However, it’s possible to alleviate some of the symptoms with medication and therapy, such as cognitive therapy, physiotherapy, vestibular therapy, vision therapy, and occupational therapy. There are also a number of lifestyle choices, such as engaging in regular exercise and eating a healthy diet, that may delay progression of symptoms and allow patients to live independently for longer.

CTE is a form of TBI caused by a buildup of tau proteins in the brain. Tau is usually a helpful protein, ensuring cells talk to each other. But in the aftermath of repeated falls, concussions, or other head trauma, the protein becomes jumbled. It can affect mood, cognition, and behavior. Over time, day-to-day things that were once routine become challenging. […] Depending upon the severity and location of the brain injury, symptoms linked to CTE can vary and may occur years or decades after head trauma. The most common signs may include: […] Cognitive: Memory problems, confusion, difficulty thinking, impaired judgment. […] Mood: Depression, anxiety, irritability, aggression. […] Behavioral: Impulsivity, violence, suicidality. […] Physical: Headaches, dizziness, tremors, difficulty balancing. […] Although there is currently no cure for CTE, medication, cognitive therapy, and lifestyle changes are the most common therapies helping people suspected to have CTE live a better quality of life. Research is ongoing to identify potential new treatments.

https://my.clevelandclinic.org/health/diseases/17686-chronic-traumatic-encephalopathy-cte
The symptoms of chronic traumatic encephalopathy can disrupt processes throughout your brain. […] As this condition worsens, it can cause disruptive or aggressive behavior. […] The symptoms of CTE tend to develop slowly and get worse over time. […] Common symptoms of CTE can include: Trouble concentrating or focusing (mild cognitive impairment). […] Changes in behavior, including sudden outbursts or explosions of anger. […] Other symptoms that can occur include: Increasingly aggressive behavior. […] Self-harming thoughts and behaviors (including thinking about and attempting suicide). […] CTE is a degenerative brain disease. That means its progressive, and the symptoms will get worse over time. […] CTE is a permanent, lifelong condition. […] Currently, the available research and understanding of CTE indicate this condition isnt deadly on its own. Instead, it causes other health concerns that negatively affect your health and well-being. […] When the effects of this condition get severe enough, it can lead to dysphagia, which is when you have trouble swallowing.

Related movement disorders. Some people develop motor neurone disease (MND) or Parkinsons disease in association with CTE. […] Researchers identified these symptoms by interviewing family members of people who were confirmed to have CTE. […] This is because CTE cant currently be diagnosed while a person is alive. The diagnosis is only confirmed by looking at the persons brain tissue after they have passed away. […] Research has also suggested that there are possibly two clinical presentations of CTE. Some people experience behavioural and mood symptoms first, while others experience cognitive symptoms first. […] The variation in CTE is partially the reason that it is difficult to diagnose. If someone develops symptoms of depression and anger issues in their 20s or 30s, it may be misdiagnosed as a psychiatric disorder.
#73 What Is CTE (Chronic Traumatic Encephalopathy)? An Overview
https://www.healthline.com/health/overview-of-chronic-traumatic-encephalopathy-cte
CTE causes symptoms similar to those of Alzheimers disease, such as memory loss and mood changes. […] It can take years for CTE symptoms to appear, but they can drastically impact quality of life by causing physical and mental impairment. […] Symptoms vary between people, but according to the National Health Service, theyre similar to those of other degenerative brain conditions, like Alzheimers. […] Symptoms tend to develop gradually after repeated blows or concussions. These symptoms may include: short-term memory loss, headaches, mood changes, erratic behavior, including aggression, depression, and suicidal thinking, increased confusion and disorientation, problems sustaining attention, brain fog, slurred speech, significant memory problems, tremor, slow movement, difficulty eating or swallowing (this is rare).
#74 Signs and symptoms of Chronic Traumatic Encephalopathy (CTE)
https://www.mymed.com/diseases-conditions/chronic-traumatic-encephalopathy-cte/signs-and-symptoms-of-chronic-traumatic-encephalopathy-cte
Generally, mood and behavioural changes are predominant during the earlier stages of CTE progression and are often noticeable in younger individuals. Cognitive impairments may begin showing signs early on, but this generally intensifies during the latter stages (when an individual is typically of an older age), becoming the dominant set of symptomatic challenges. For others, this course of symptom development may occur the other way around. Thus, the clinical course of CTE is not yet precisely outlined and may vary in certain individuals. […] Not every identified symptom relating to how a person thinks, feels, acts and moves is experienced by all sufferers. The aforementioned are merely identified as being most likely, following thorough research so far. What most medical professionals agree on is that a person affected by CTE may experience symptoms in at least one or more of the symptom presentation domains mood, behaviour, cognitive and motor and that those experienced are likely to intensify as the disease progresses in severity.

Symptoms of CTE: Symptoms can vary depending on the extent of the trauma and which areas of the brain are involved. Symptoms may include- memory loss, mood changes, confusion, and difficulty with thinking and speech. […] Here is a list of common symptoms that tend to occur with CTE: short-term memory loss, changes in mood â such as frequent mood swings, depression, and feeling increasingly anxious, frustrated, or agitated, increasing confusion and disorientation, difficulty thinking and making decisions, slurred speech or dysarthria, significant memory problems, parkinsonism â including tremor, slow movement, and muscle stiffness, difficulty eating or swallowing (dysphagia). […] Early intervention is key to preventing significant brain damage. With correct and quick interventions, we are more likely to be able to prevent long term symptoms. This will help protect brain and body function to reduce the overall impact of the injury.

Chronic traumatic encephalopathy (CTE) is a brain disorder likely caused by repeated head injuries. It causes the death of nerve cells in the brain, known as degeneration. CTE gets worse over time. […] Symptoms of CTE are thought to include trouble with thinking and emotions, physical problems, and other behaviors. It’s thought that these develop years to decades after head trauma occurs. […] CTE symptoms don’t develop right after a head injury. Experts believe that they develop over years or decades after repeated head trauma. […] Experts also believe that CTE symptoms appear in two forms. In early life between the late 20s and early 30s, the first form of CTE may cause mental health and behavioral issues. Symptoms of this form include depression, anxiety, impulsive behavior and aggression. The second form of CTE is thought to cause symptoms later in life, around age 60. These symptoms include memory and thinking problems that are likely to progress to dementia. […] The full list of signs to look for in people with CTE at autopsy is still unknown. There’s also little known about how CTE progresses.

Chronic traumatic encephalopathy (CTE) is increasingly in the news often in connection to severe mood and behavior changes in former athletes. […] Like Alzheimers and Parkinson’s disease, CTE is a neurodegenerative condition. This brain disease occurs when the nerve cells that help you think, feel, and move gradually break down. When these cells stop working, patients may experience personality changes and lose memory and muscle control. […] CTE is characterized by four stages of symptoms: Stage 1: Short-term memory loss; mild aggression and depression; headaches. […] Stage 2: Severe depression, outbursts, and mood swings. […] Stage 3: Aggression; apathy; memory loss; lack of spatial awareness; executive dysfunction (inability to successfully complete activities that require time management, organization, and problem-solving).

This is the final stage of the disease, and it is the most severe. During this stage of CTE, patients begin to experience severe cognition problems and memory loss that leads to full-blown dementia. During stage four, CTE begins to affect movement. The patient starts to develop Parkinsonism, an umbrella term that describes slowed movements caused by a decline in brain function. The patient may suffer from rigidity and tremors. […] Unfortunately, there is no way to decrease the progression of the disease.
#81 Current Understanding of Chronic Traumatic Encephalopathy
https://pmc.ncbi.nlm.nih.gov/articles/PMC4255271/
Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease thought to be associated with a history of repetitive head impacts […] Clinical symptoms of CTE generally present years or decades after exposure to trauma. […] Evidence to-date suggests that CTE presents clinically with symptoms in one or more of four possible domains: mood, behavior, cognition, and motor. […] Commonly noted mood features include depression, irritability, and hopelessness. Behavioral features may include impulsivity, explosivity, and aggression. Cognitive features can include memory impairment, executive dysfunction, and in severe cases dementia. Motor features, including parkinsonism, ataxia, and dysarthria, appear in a subset of cases, predominantly boxers. […] Two distinct clinical presentations of CTE have been described in a recent study by Stern et al., substantiating evidence from earlier literature regarding this possibility.

Here, we present the advances in the neuropathological diagnosis of CTE culminating with the development of the NINDSNIBIB criteria, the multiple international studies that have used these criteria to report CTE in hundreds of contact sports players and others, and the evidence for a robust doseresponse relationship between RHI and CTE. […] The clinical features associated with CTE pathology include cognitive, mood, behavior, and motor impairments, with dementia common in severe disease. […] Younger individuals tend to present with mood and behavior symptoms, whereas older individuals more commonly present with cognitive impairment and executive dysfunction. […] The presence of dementia followed an age-dependent progression, and older age at death was associated with increased odds for having dementia. […] The preponderance of the evidence suggests a high likelihood of a causal relationship between RHI and CTE, a conclusion that is strengthened by the absence of any evidence for plausible alternative hypotheses.
